UTILE

Kazenari Rei was an ordinary human, once lost in the despair of his mundane life. But when the collapse of his world arrived — powered by the cataclysmic force known as Honkai End — Rei’s soul was chosen for rebirth. Not as a hero. Not as a savior. But as something the world of High School DxD is not prepared for.

Armed with the power to awaken Spirits in ordinary humans — a twisted hybrid of the Date A Live system and Honkai resonance — Rei now walks among devils and angels as an unpredictable force. With a personality as calm as flowing water but wrath as deadly as a collapsing star, Rei keeps to the shadows, choosing neutrality… for now.

Eclipse of the Spirit: The Reincarnated Flame

In the undercurrents of the world's ley-lines, something old stirred. Something ancient.

Vereth's Loom Crypt, buried beneath twelve spirit planes, was no longer stable. The threads he once controlled now whispered back, refusing alignment. Yet one remained taut. Red. Pulsing. Bound to a name that hadn't been spoken in over a millennium.

Spirit Core Nexus – Rei's Sanctuary

Ten flames hovered in harmony, encircling Rei. Each flickered with purpose. Each told a story. But none could calm the dissonance now piercing the realm.

Karasu cawed urgently, feathers flaring. "Vereth has unsealed the final lock. Vildras moves."

Mireille stepped forward, projection screen floating beside her. "We've intercepted fragments of prophecy from the collapsed Gnostic fragments. Vildras isn't just destruction. It's permanence. When it burns, the soul cannot be reborn."

Rei narrowed his eyes. "So even flame dies?"

Eirenne nodded. "It's called the Ash Verdict. And if Vildras activates in full, every integrated spirit within you could be... erased."

A hush fell. Then Rei stood. "Then I meet it before it finishes waking."

Path to the End — The Vale of Last Voices

The final chamber was not guarded by monsters. It was guarded by echoes.

Every step Rei took across the obsidian vale, voices swirled around him—fragments of those he'd failed.

"Why didn't you save me?" "You left me in the flames." "You were supposed to be our hope."

Rei didn't flinch. But he did listen.

"They still shape me," he whispered. "Even in sorrow."

At the vale's heart: a pyre that burned backward—flames consuming light and giving birth to shadow.

Vildras stood within. A woman-shaped inferno of crimson ash and black wind. Her body flickered constantly, as though she could not decide on one form.

"You dare bring life into the shrine of the unmade?" she asked.

"I bring memory. Not for salvation. But to remember why we fight."

Vildras attacked. No fanfare. Just obliteration.

Reality cracked as she threw her scythe. It sliced through timelines, striking down versions of Rei that had never existed. Each death sent a shock through the system.

Mireille screamed into the comms. "System integrity at 53%! Rei, stop!"

But Rei stood again. Every step forward cost a fragment of self—but he kept walking.

He ignited Iskaria's frost. Nyssara's void. Thrael's foundations. Even Liora sang in dissonant resonance.

"You are a flame that forgets its cost," she hissed.

"No," Rei growled, "I'm the flame that remembers everything."

Then he did what the system never expected. He offered himself. Fully. Unshielded.

"Take me. Burn what must be burned. If what remains is still me—then you never ruled."

Vereth screamed. His threads snapped, red lightning fracturing the loom's heart.

"YOU WERE NEVER MEANT TO REACH HER!"

Rei's voice echoed across the planes.

Rei looked out across the stars. He wasn't done. Not until every forgotten voice had a name again.
